Serialize scan notifications and surface failures even when database error persistence fails. Recover interrupted scans independently of auto-scan, retain their checkpoints, and collect matching Android process-exit details on restart.
The AutoMix tests slept about 17 s of wall time waiting for fades, tempo
recovery and "nothing happens" windows, and the haptics tests 1.15 s.
fake_async is not a direct dependency, so the analyzer rejects importing
it. Haptics tests run as testWidgets on the binding's FakeAsync clock,
which also drives the PlaybackState position extrapolation.
The AutoMix player shares process-wide runtime state (the listening
recorder and personalization write chains), so a FakeAsync zone that
stops after one test would strand later tests. test/support/virtual_time
adds a zone with virtual timers and real microtasks instead: setUp builds
the player in that zone, and fakeTimeTest runs a body with its timers
fired in due order, skipping idle time. Pending timers continue on real
time afterwards.
AutoMix reads its fade and readiness clocks through autoMixStopwatch,
which defaults to Stopwatch.new; tests point it, and the native fake's
deck clocks, at the virtual clock. Test bodies and assertions are
unchanged.
The lookup cache test waited out the 500 ms production debounce four
times (2.7 s). A @visibleForTesting setter lets the test use a 10 ms
debounce while keeping the same 50 to 250 ms margin after the timer
fires for the background encode. The production default stays 500 ms
and the assertions are unchanged.
The Dart incremental ingestion branch runs only when
PlatformBridge.supportsCoreBackend (Platform.isAndroid || Platform.isIOS)
is false. Its useSnapshotBridge flag required Platform.isAndroid, so it
could never be true there, and the native handlers for
scanSafTreeIncrementalFromSnapshot and
scanLibraryFolderIncrementalFromSnapshot are already gone.
Remove the flag, both PlatformBridge methods, and
LibraryDatabase.writeFileModTimesSnapshot(Map), whose only other user was
test/library_scan_snapshot_test.dart (deleted with it). The live native
snapshot path (writeNativeFileModTimesSnapshot) and the host-test branch
with _backfillLegacyFileModTimes are unchanged.
The map and list lookup caches had twin entry classes and twin put and
prune helpers that differed only in the value type. Replace them with
_BridgeCacheEntry<T>, _putMemoryCached<T> and _pruneExpiredBridgeCache<T>.
Each cache keeps its own map, TTL and budget accounting; the byte estimate,
shared budget constants and oldest-first eviction are unchanged.
LibraryCollectionsNotifier carried about 130 lines of File and Directory
work for playlist covers. PlaylistCoverStore now owns the playlist_covers
directory, the <playlistId>.jpg normalization with its temp file, the
backup restore copy or base64 write, and the delete helpers. The
directory is still resolved through getApplicationSupportDirectory on
each call, at the same points as before.
The notifier keeps setPlaylistCover, removePlaylistCover,
exportPlaylistCoverFiles and restoreFromBackup with unchanged signatures,
mutation ordering and error handling: a failed restore of one cover still
drops that cover path, removePlaylistCover still propagates delete
errors, and replacing a cover still deletes the old file quietly.
The cache management page walked and deleted directories itself. Move
_scanDirectory and _clearDirectoryContents verbatim into
CacheMaintenanceService.scanDirectory and clearDirectoryContents in
lib/services/cache_maintenance_service.dart, with _DirectoryStats
becoming the public DirectoryStats it returns.
The page calls the service at the same points with the same arguments,
so scan concurrency, the 24-entity delete chunks, the directory
re-creation after clearing and every action key are unchanged.
The card ran ffprobe, both FFmpeg sessions, SAF temp copies, the
native spectral-cutoff job and its cancellation inside State. Move that
pipeline verbatim into AudioAnalysisRunner in
lib/services/audio_analysis_runner.dart together with the private
per-run records from the widget's models part, which is now empty and
removed.
The card keeps request ids and every setState. The runner takes a
`bool Function() isCancelled` that the card builds from the same
`!mounted || requestId != _spectrogramRequestId` test, polled at the
same points that used to call _checkAnalysisRequest. cancel() and
dispose() run the jobs invalidate/dispose, network cancel and native
job cancel in the original order.
Subprocess order, temp file names and cleanup, SAF copy and the native
data job payload are unchanged.
The card owned the bundle storage (key derivation, {key}.json,
{key}.png and {key}_ch{n}.png, the shared trim budget) as static
members, and the cache page spelled the audio_analysis_cache directory
literal twice more.
Move the storage verbatim into AudioAnalysisDiskCache next to the
existing lease/trim policy. AudioAnalysisDiskCache.directoryIn is now
the only place that names the directory; the card's cacheDir and both
cache page call sites use it, with the page keeping its non-creating
behavior and await order. loadFromCache takes the card's network input
as a parameter instead of reading the field.
The 63-bit FNV-1a cache key stays local: lib/utils/hash_utils.dart
fnv1a32 uses a different basis, prime and width, so reusing it would
rename every cached bundle on devices.
The audio analysis card mixed FFmpeg argument builders, astats and
metadata parsers and the spectral cutoff estimator with widget state.
Move them verbatim into lib/services/audio_analysis_ffmpeg.dart so the
runner and cache can depend on them without importing a widget.
The parsers return ChannelAnalysisStats, so the two public result
models (AudioAnalysisData, ChannelAnalysisStats) move verbatim from the
widget's models part into lib/services/audio_analysis_models.dart. The
per-run private records stay in the part for now.
Only two names change: the unsupported-codec exception loses its
leading underscore because the widget and the future runner live in
different libraries, and the in-class _parseChannelStats becomes the
top-level parseChannelStats. The widget re-exports both service files,
so tests and importers are unchanged.
library_database_models and ffmpeg_models are plain data types, so they live in
models (re-exports stay at the old paths). deleted_library_files uses providers
and download_progress uses provider state, so both move to providers, and
ffmpeg_reenrich is a service. models no longer import from services for these.
Batch actions, clickable metadata, playback, auth launcher, action forms and
the glass warmup drive UI flows, so they belong with the controllers. Files
with more than three importers (or an importer that must stay untouched) keep
a one-line re-export at the old path.
Add fnv1a32 in hash_utils.dart for the scan output name (UTF-8 bytes) and
qualityVariantStagingLabel (UTF-16 code units). Unit tests pin outputs
computed from the original inline code.
The progress notification formatted megabytes inline with the same
expression as formatMegabytes (one decimal, power-of-two scaling, so the
double result is identical). It now calls the helper. No output change.
The same startsWith check was inlined in 21 places across services and
providers. They now call the existing helper, which has identical
semantics (no trim, no case folding). No behavior change.
The class moves verbatim and is re-exported from music_player_service.dart.
The toJson/fromJson artwork round trips stay: toJson drops non-positive
numbers, blank formats and empty artwork, so a copyWith would not be an
exact replacement for them.
LibraryIngestionStore holds scan and incremental ingestion writes with
bodies unchanged. LibraryDatabase keeps thin delegating methods with the
same public signatures and passes in its connection and the lazy History
attachment. SQL text is unchanged.
Mirror the library_schema and library_row_mapper split: HistorySchema owns
create, upgrade, index creation and backfills, HistoryRowMapper owns the
JSON/row mapping and the derived normalized and queue-sort columns. SQL text
is unchanged. Tests that read the history CREATE TABLE and index text now
read history_schema.dart.
Top-level helpers and secondary classes (codec isolates, cache entries,
event and SAF models, the native worker job state and the NDJSON scan
file) move verbatim into part files grouped by concern. The
PlatformBridge class body is unchanged apart from three region comments
over groups that were already contiguous.
platform_bridge.dart was one 2900-line file mixing eight concerns; the
static class cannot be split without changing its type, so this moves
what can move mechanically and leaves the class intact for call sites
and the channel mocks in tests.
The log buffer polls the native backend, so isFromGo, the Go log polling
methods and their private state now use native names. Comments that still
described the backend as Go are reworded. No string literals changed.
Delete Dart members that have no reference in lib, test or integration_test:
unused player configuration helpers and event streams, two PlatformBridge
wrappers, database and export helpers, the unused global logger and the
now pointless 'hide log' imports.
Check service liveness while monitoring newly started native runs, matching the recovery protection already present during adoption. After three consecutive dead-service probes, reconcile completed results, requeue in-flight items and release the run instead of polling a stale running snapshot indefinitely.
Cover stale snapshots, transient probe failures, paused workers, run isolation, startup timeout and sequential verification reconciliation. Related queue and verification validation: 155 tests passed; scoped analyzer and formatter clean.

Provider and decryption extensions describe the downloaded container, not
its audio codec. A decrypted M4A/MP4 can still carry FLAC, so a requested
FLAC output now reaches the codec probe instead of being preserved early.
Lossy streams keep their native container and still receive metadata.
